Question

The ratio of the measures of a triangle are 1 : 2 : 1 . Find the measures of the angles .

Answer 1

✌HEY DUDE✌
Let the angles be 1x ,2x and 1x
1x + 2x + 1x = 180°(ASP of triangle)
4x = 180°
x = 45°
Therefore
angle 1 = 1x = 45°
angle 2= 2x= 90°
angle 3= 1x = 45°
☺HOPE THIS HELPS YOU!!☺

Answer 2

$\textbf{1x + 2x + 1x [ Angle sum property of a triangle ]}$

$4x = 180°$

$x = 45°$

∴ Angle,

$\: \: \: \: \: \: \: \: \: \: ⇒ \: \: \: \: \: \: \: \: \: \: 1 (1x) = 45°$

$\: \: \: \: \: \: \: \: \: \: ⇒ \: \: \: \: \: \: \: \: \: \: 2 (2x) = 90°$

$\: \: \: \: \: \: \: \: \: \: ⇒ \: \: \: \: \: \: \: \: \: \:3 ( 1x ) = 45°$
